Description of the Invention: [Technical Field] The present invention relates to a media file generating method and a media playing method, and more particularly to a method for generating and playing a 3D coordinate media file. [Prior Art] Generally, a series of frames (images) of a video system along a time axis. When the video is played, the frame will be displayed on the display device, such as the computer screen, according to the timeline. Conventionally, a 2-coordinate media file is used to record media/video, where one coordinate represents a time coordinate and the other coordinate represents a frame coordinate. The frame can be 2D (2D) image or 3D (3D) graphic. When the frame is a 3D graphic, the video is called 3D video. However, since only the time and frame coordinates are provided, the media file containing the 3D video is still a 2-coordinate media file. Figure 1 shows a conventional 2-coordinate media file. As shown in Figure 1, the media ® file has two coordinates, time and frame. The media file records the frame along the timeline. For example, the time point T〇 records the frame F〇, the time point T! records the frame F!, the time point T2 records the frame F2, and so on. The media file can be input to a display device such that the media file can be played via a broadcast frame along the time axis. KVM Switch is a hardware device that allows users to control multiple hosts, such as computers, through a keyboard, display and mouse. The KVM switch will transmit a message between the host and the keyboard, monitor and mouse. In some cases, each host can be a video source, and the KVM switch is received by the host (video source) and the frame is recorded. Conventionally, the KVM switch records a 2-coordinate media file for each video source. In other words, if 8 hosts are coupled to the KVM switch, 8 media files will be generated, in which the frames of the individual video sources will be captured and recorded in the corresponding media file along the timeline. In some embodiments, management of media files, such as alignment and recovery, is very difficult if a KVM switch has multiple video sources. In addition, when the video source is played, since the frames of the individual video sources in the corresponding media file are recorded independently, the frames between different video sources have a chance to be out of sync. SUMMARY OF THE INVENTION In view of the above, the present invention provides a media file generating method and a media playing method. A media file generating method according to an embodiment of the present invention. First, at least one frame is received by at least one view source. Thereafter, a media file is generated by recording the received frame along the time axis with a particular number corresponding to the video source transmitting the frame. A media playing method according to an embodiment of the present invention. First, a media file is obtained, wherein the media file records at least one frame of a video source and a specific number corresponding to the video source along the time axis. This media file is then played by playing the frame according to the specific number along the timeline. The media file generating method of the embodiment of the present invention is applicable to a device having at least one 200926155 video source. First, at least one first frame is captured by a first video source, and at least one second frame is captured by a second video source. Thereafter, a media file is generated by recording a first frame with a first specific number of the first video source and a second frame and a second specific number of the corresponding second video source along the time axis. The above method of the present invention can be recorded in physical media through code. When the code is loaded and executed by the machine, the machine becomes the means for carrying out the invention. The above described objects, features, and advantages of the present invention will become more apparent from the following description of the appended claims. [Embodiment] Fig. 2 shows a media recorder for generating a 3-coordinate media file in accordance with an embodiment of the present invention. As shown in FIG. 2, the media recorder 200 is coupled to a plurality of video sources VS1, VS2, ..., VSn. In some embodiments, the video source can be a channel of the KVM switch, and the individual video sources can correspond to different KVM switches. The media recorder 200 receives the frame from the video source and generates a 3-coordinate media file 210. In addition, when the corresponding operation of the frame, such as the keyboard and/or the mouse, is performed on the switch, the operation data of the corresponding operation is also received by the video source and recorded in the 3-coordinate media file 210. The format of the 3-coordinate media file 210 will be described later. Figure 3 shows a method of generating a media file in accordance with an embodiment of the present invention. 7 200926155 In step S31, there is a specific material from the source of the individual video source to the 3_seat (4) body = video to see if there is any choice ~ 乂 win ^: as in step S33 〇 'determine any source as nit source Above the box. If yes (NO in step S330), the process returns to step S330. If the step S34 is performed, the result is obtained by step = step and the operation data is deflated and the details are made. Code together # # 5 The specific number of the video source of the Lin Wei box ❹ L II / coordinate media file. Afterwards, the process returns to step JL. In some embodiments, if the operation data is directly integrated into the frame and transmitted by the video source, the steps (4) and S340 can be omitted and the operation data can be automatically The specific number of the video source of the frame and the corresponding transmission frame is recorded in the 3_coordinate media file. It is worth noting that the method of generating the 3-coordinate media file has a time-sharing mode and a time span. Time-overriding mode. In the time sharing mode, frames from individual video sources are simultaneously taken and recorded in the 3-seat media slot. For example, at each point in time, each video source will Capture a frame. In the time span mode, 'the frame of the individual video source is captured at different time points' and recorded separately to the media file. For example, only one frame at a time point will be Drawing from all video sources. Figure 4 shows an example of a 3-coordinate media weight in a time sharing mode in accordance with an embodiment of the present invention. The frame of the source is captured and recorded to the 3-coordinate media file, where 'VS0, VS1 200926155 and VS2 are different specific numbers of the video source. At the time point τ〇, frames F〇〇, Fio and F20 The video sources VS0, VS1 and VS2 are respectively taken. At the time point, the frames Fo!, F„ and F21 are respectively taken by the video sources VS0, VS1 and VS2. At time point τ2, frames F〇2, Fi2, and f22 are captured by video sources VS0, VS1, and VS2, and so on. It is noted that one less operation is performed on the frame f22 of the video source VS2, and the corresponding operation is that the magazine 22 and the frame Fn are recorded to the 3-coordinate media file. Similar to the phase 'at least—the operation is performed on the frame of the video source VS1, FUn_2), the dried & data 0DKn-2) and the frame F1(n_2) are recorded to the 3-coordinate media. An example of a frame in a time span mode in accordance with an embodiment of the present invention. As shown in Figure 5, the messages from different video sources are simultaneously taken and recorded to the 3_ coordinate media file. At some point 2, only one frame of the video source was captured. In a 3-seat video source can be recorded as recorded in the time sharing mode and some video sources can be recorded in the time j slot in the time span mode. For example, the video source (4) and VS1 can be recorded as a 3-coordinate media file in the VS3 format and the video source VS2 is recorded in the 6th (fourth) time span mode as a 3. coordinate media weight. In an embodiment, a media retrieval method according to an embodiment of the present invention. Here * to carry out the relevant tube = body slot. For example, (4) = step-off, providing a 3-party or specific display device or: #定号, - specific time point, and /200926155 Figure 7 shows the media player according to the embodiment of the present invention, going to step S710, A 3-coordinate media file is provided to a TM MPEG playback device for playback. In step S720, the frame in the 3-coordinate media file is played according to a time along the time axis. In some embodiments, If the 'number' corresponds to a specific number of a specific video source, then the corresponding number 4, _· ❹ box will be retrieved from the 3-coordinate media file and will be released along the time. It is worth noting that the corresponding number is The box will be displayed in a particular display device, or a corresponding display area (or virtual device) of one of the corresponding numbers in the corresponding one of the line numbers. If = a specific number is specified, the 3-coordinate media When the slot is played, the frame of all the specific numbers (video sources) in the coordinate body = will be retrieved, and will be broadcast simultaneously in the corresponding specific display device or specific display = domain along the time axis.
